The existence of recorded accelerograms to perform dynamic inelastic time history analysis is of the utmost importance especially in near-fault regions where directivity pulses impose extreme demands on structures and cause widespread damages. But due to the scarcity of recorded acceleration time histories, it is common to generate proper artificial ground motions. In this paper an alternative ...

Background: One of the main problems especially in operating room and monitoring devices is measurement of Blood Pressure (BP) by sphygmomanometer cuff.Objective: In this study we designed a new method to measure BP changes continuously for detecting information between cuff inflation times by using vital signals in monitoring devices. This will be achieved by extraction of the time difference ...

OBJECTIVE The aim of this study was to evaluate the accuracy of a new blood pressure (BP) measurement method (Pulse method). METHODS This study enrolled 45 patients for selective percutaneous coronary intervention (PCI) via right radial artery. A BP device using either oscillometric (Microlife 3AC1-1) or Pulse method(RG-BP11)was used. At the beginning of each PCI, intra-radial BP was measured...

In this paper, the numerical technique based on hybrid Bernoulli and Block-Pulse functions has been developed to approximate the solution of system of linear Volterra integral equations. System of Volterra integral equations arose in many physical problems such as elastodynamic, quasi-static visco-elasticity and magneto-electro-elastic dynamic problems. These functions are formed by the hybridi...

a highly sensitive differential pulse polarographic (dpp) method has been developed for the determination of trace amounts of osmium, based on the catalytic effect of osmium (viii) on the oxidation of pyrogallol red (pgr) by sodium bromate at ph 7.00 and 25.0 0.1 ? c. the reaction rate was monitored by measuring the differential pulse cathodic current of the oxidation product of pgr and bromate...

A simple method for the generation of ultrashort pulse train with high-repetition-rate is proposed and demonstrated numerically. OCIS codes: (320.5520) Pulse compression; (320.5540) Pulse shaping

CELP coders using pulse codebooks for excitations such as ACELP[1] have the advantages of low complexity and high speech quality. At low bit rates, however, the decrease of pulse position candidates and the number of pulses degrades reconstructed speech quality. This paper describes a method for adaptive allocating of pulse position candidates. In the proposed method, N e cient candidates of pu...

Previously a method has been proposed for a high-performance compression method designed expressly for compressing intercepted radar pulse trains for the purpose of locating the transmitter. The method relies on gating pulses, putting them into a pulse matrix and then using the singular value decomposition (SVD) to compress the signal data. The pulse gating step, however, generated a sequence o...

A general method to design continuous-time Sigma{ Delta ((() modulators with delayed return-to-zero (RZ) feedback pulse is presented. This method can be applied to design modulators with any arbitrary delay and pulse width. It is shown that the key-point to avoid the degrading eeects of clock jitters, is to generate a low jitter feedback pulse-width, using a monostable multivibrator.

We introduce a noninterferometric single beam method to characterize and compensate the spectral phase of ultrashort femtosecond pulses accurately. The method uses a pulse shaper that scans calibrated phase functions to determine the unknown spectral phase of a pulse. The pulse shaper can then be used to synthesize arbitrary phase femtosecond pulses or it can introduce a compensating spectral p...
